Electro-Voice Speaker System Balanced XLR Outputs, AES/EBU Digital Input, Balanced XLR Thru

28 – Balanced XLR Outputs

Each output channel has an electronically balanced XLR connector for connection to system amplifiers. Each output channel can output different frequency ranges depending on its assignment and cross-over settings.

Care must be taken to assure that each output is connected to an appropriate amplifier and loudspeaker to avoid damage or unexpected results. Note that a new preset may change the assignment of channel and its frequency range. For instance an output assigned to Hi frequency speakers in one preset, may be assigned as a sub output in another. See chapter “Configurations of the DC-One” for connection examples.

29 – AES/EBU Digital Input

In addition to the analog audio inputs, an AES/EBU digital stereo input is provided and selectable in the Setup menu. The input conforms to IEC standard 60958 Type I. Connections must be made with three-conductor, 110-Ohm, twisted pair cabling and an XLR connector.

30 – Balanced XLR Thru

Each analog audio input is connected to an electronically buffered and balanced output as a through connector. The signal does not go undergo any digital conversion or processing. These connectors are used to pass input audio to a second DC-One used as a slave or to other audio inputs in the system.

31 – Balanced XLR Inputs

Each input has an electronically balanced, locking XLR connector. In stereo or dual modes, connections to both inputs must be made. In mono modes, only one connection need be made, typically to Input A.

32 – -6dB Pad

Input levels to the DC-One can be reduced -6dB prior to the A/D converter to compensate for higher-level output from mixers and other audio devices. For ideal signal to noise performance when connecting the DC-One to high output level devices engage the -6dB pad rather than turning down the output of the connected device. The DC-One’s Input Level Meters (2) will indicate incoming signal level and whether attenuation is required.
